AC question
Very cold this morning 28° and usually when I turn on fan for heat the AC button light comes on and I punch it off. Today it didn't come on but heat was on as expected. Punch AC button and it flashes a few times and goes out. Question, was this because it was so cold? Ran codes and have none. Thinking is was because it was so cold that AC light and compressor wouldn't come on. No oem manual to review. Thoughts, thanks

[QUOTE=C5 Diag;1602726445]Yes, if ambient temperature is too low the AC will not work..it is one of the “inputs” the PCM uses to determine if will let the AC turn
Thanks for clarifying, was hoping that was the reason.
